}
```

하지만, 다중 본문 매개변수 역시 선언할 수 있습니다. 예. `item`과 `user`:

{* ../../docs_src/body_multiple_params/tutorial002.py hl[22] *}

이 경우에, **FastAPI**는 이 함수 안에 한 개 이상의 본문 매개변수(Pydantic 모델인 두 매개변수)가 있다고 알 것입니다.

그래서, 본문의 매개변수 이름을 키(필드 명)로 사용할 수 있고, 다음과 같은 본문을 예측합니다:

```JSON
{
    "item": {
        "name": "Foo",

    testSortDescending(new int[] {1, 2}, new int[] {2, 1});
    testSortDescending(new int[] {1, 3, 1}, new int[] {3, 1, 1});
    testSortDescending(
        new int[] {GREATEST - 1, 1, GREATEST - 2, 2}, new int[] {GREATEST - 1, GREATEST - 2, 2, 1});
  }

  private static void testSortDescending(int[] input, int[] expectedOutput) {
    input = Arrays.copyOf(input, input.length);
    UnsignedInts.sortDescending(input);

The `lifespan` parameter of the `FastAPI` app takes an **async context manager**, so we can pass our new `lifespan` async context manager to it.

## Alternative Events (deprecated) { #alternative-events-deprecated }

O parâmetro `lifespan` da aplicação `FastAPI` aceita um **gerenciador de contexto assíncrono**, então podemos passar para ele nosso novo gerenciador de contexto assíncrono `lifespan`.

…и передаст возвращённое значение как значение зависимости в нашу *функцию-обработчике пути* в параметр `fixed_content_included`:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[22] *}

/// tip | Совет

Все это может показаться притянутым за уши. И пока может быть не совсем понятно, чем это полезно.

Эти примеры намеренно простые, но они показывают, как всё устроено.

	{ETag: "a7d414b9133d6483d9a1c4e04e856e3b-2", AWSETag: "a7d414b9133d6483d9a1c4e04e856e3b-2"},                                                             // 2
	{ETag: "7b976cc68452e003eec7cb0eb631a19a-10000", AWSETag: "7b976cc68452e003eec7cb0eb631a19a-10000"},                                                     // 3

checker(q="somequery")
```

...and pass whatever that returns as the value of the dependency in our *path operation function* as the parameter `fixed_content_included`:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[22] *}

/// tip

All this might seem contrived. And it might not be very clear how is it useful yet.

These examples are intentionally simple, but show how it all works.

这样，即便我们的*路径操作函数*将会返回包含密码的相同输入用户：

{* ../../docs_src/response_model/tutorial003_py310.py hl[24] *}

...我们已经将 `response_model` 声明为了不包含密码的 `UserOut` 模型：

{* ../../docs_src/response_model/tutorial003_py310.py hl[22] *}

因此，**FastAPI** 将会负责过滤掉未在输出模型中声明的所有数据（使用 Pydantic）。

## 在文档中查看

当你查看自动化文档时，你可以检查输入模型和输出模型是否都具有自己的 JSON Schema：
